New Mercedes-Benz CLS 63 AMG

AMG slots bi-turbo V8 into the CLS - planet is saved (for now)

With up to 557hp and 590lb ft of torque to call on, it's no wonder M-B puts the new CLS 63 AMG's fuel consumption figure near the top of its press announcement for the new model.

The number is 28.5mpg, which is a level of frugality we find frankly unbecoming in a fire-breathing monster from Affalterbach. Surely something in the low teens would be more appropriate - at this rate everybody will want one...

A 32 percent improvement in fuel consumption is only one of the eye-catching numbers associated with the latest CLS range-topper. The car gets the new twin turbo engine we tried in the (also fabulously frugal) S63 recently, which means 525hp and 516lb ft in standard guise, or the figures mentioned at the top of the article when the Performance Pack is fitted. (The latter raises charge pressure from 1.0 to 1.3 bar and shaves 0.1secs off the standard 4.4sec 0-62mph time.) The transmission is Merc's admirable 7spd MCT unit, which doubtless does quite a lot to help in all respects.

With exterior design inspired by the SLS AMG, the new machine is distinguishable from lesser CLSs by a bespoke bonnet, wider arches and AMG front apron with black painted cross-member. There's also a special diffuser insert, and twin chrome tailpipes.

The new car goes on sale in the UK in May next year, so get those deposits in now!
